“…13 It is theorized that with a high Hct, timed diffusion of glucose from blood onto the test strip is delayed as a result of the number of RBCs, which leads to spuriously low glucose values. Glucose concentrations in venous samples may underestimate those in arterial samples by 15%, and capillary samples also have lower blood glucose concentrations than do arterial samples.…”

“…The calibration of the glucometer and performance checks were carried out according to the manufacturer's instructions. Some glucose re¯ectance meters are sensitive to environmental factors and in particular the results obtained are altered by haematocrit 11,12 , pH 13 and pO 2 14 . However, the glucometer used in this study is not in¯u-enced by these variables.…”

Objective To compare plasma glucose in pregnant women living at very high altitude; pregnant women living at sea level; non-pregnant women living at very high altitude; and non-pregnant women living at sea level.Design Cross-sectional study. Participants Ninety-four pregnant women attending for routine antenatal care at 8±42 weeks of gestation in Cerro de Pasco, Peru which is situated 4370 m above sea level; 122 pregnant women in Lima, which is at sea level; 22 non-pregnant women in Cerro de Pasco; and 31 non-pregnant women in Lima. Methods Plasma glucose concentrations were measured in samples obtained from the antecubital vein between 8 am and 10 am after an overnight period of fasting for at least 10 hours. Results Fasting plasma glucose was lower in women at high altitude than in those at sea level, and in both groups the level was lower in pregnant women than in non-pregnant controls. The body mass index was not signi®-cantly different between all four groups, and it did not have a signi®cant independent contribution in explaining the variance in fasting plasma glucose.Conclusion Women native at high altitude have lower plasma glucose concentrations before and during pregnancy than those at sea level.

“…It has been shown that haematocrit may affect the results of blood glucose measurements with glucose meters (6,7). In this study both meters were affected by variations in haematocrit, showing an inverse relationship between glucose results and haematocrit values except for the Accutrend ® sensor at low blood glucose concentrations, where a slight opposite effect was seen ( Fig.…”

The performance and practicability of 2 blood glucose meters (Glucocard Memory 2 and Accutrend sensor) were evaluated. Both glucose meters produced acceptably precise results in the hyper- and normoglycaemic concentration ranges. In the hypoglycaemic concentration range, the imprecision of Accutrend sensor was much higher than recommended by the American Diabetes Association. Within-run coefficients of variation for Glucocard Memory 2 were 6.3%, 3.9% and 2.4% at glucose concentrations of 1.7 mmol/l, 5.8 mmol/l and 11.7 mmol/l, respectively: for Accutrend sensor these were 15.2%, 5.0% and 1.2% at respective concentrations of 0.9 mmol/l, 4.2 mmol/l and 19.6 mmol/l. Between-day coefficients of variation for Glucocard Memory 2 were 4.8% and 3.5% at glucose concentrations of 3.9 mmol/l and 17.2 mmol/l, respectively and for Accutrend sensor they were 3.8% and 2.9% at glucose concentrations of 3.8 mmol/l and 18.7 mmol/l, respectively. Results were linear over a range of 1.6 mmol/l -29.7 mmol/l for Glucocard Memory 2 and 1.6 mmol/l -33.3 mmol/l for Accutrend sensor. Results of both blood glucose meters correlated closely with the hexokinase/glucose-6-phosphate dehydrogenase laboratory method. Ninety-eight percent of both Glucocard Memory 2 and Accutrend sensor results were within 20% of the comparison method values. Ninety-three percent of the Glucocard Memory 2 and 96% of the Accutrend sensor results were within 15% of the comparison method results. An inverse relation between the glucose readings and haematocrit values was observed for both blood glucose meters in the hyperglycaemic range and this effect was more pronounced for Accutrend sensor. In the normo- and hypoglycaemic ranges the effect was insignificant and absent, respectively. Minimum sample volume for Glucocard Memory 2 was 3 microliters and for Accutrend sensor it was 9 microliters. Lower sample volumes gave erroneous results. Presenting more than the required volume had no effect on results.
